Title: Magnetic scale and its preparation
Inventor: MYOGA OSAMU
IPC: G01B7/00
Filed: 1984-07-24
Abstract: PURPOSE:To enhance the corrosion resistance of a magnetic scale, by implanting a Ni-ion in the entire peripheral surface or a part of an Fe-Co-Mn-C alloy wire material so as to reach a depth of 10-50nm. CONSTITUTION:A Ni-ion is implanted in the entire peripheral surface or a part of an Fe-Co-Mn-C alloy wire material so as to reach a depth of 10-50nm to prevent the deterioration in the corrosion resistance of said wire material. In the case of a manufacturing process A according to the order of heat treatment-ion implantation-fixation of wire material and a manufacturing process B according to the order of ion implantation-heat treatment-fixation of wire material, the ion is implanted in the entire peripheral surface of the wire material while said wire material is rotated. In the case of a process C of fixation of wire material-heat treatment-ion implantation and a process D of fixation of wire material-ion implentation-heat treatment, the ion is implanted in a part of the wire material without rotating said wire material. By this method, high coercive force can be imparted to the wire material and the application range of a magnetic scale can be widened.

Title: Quick cooling device for liquid
Inventor: YOSHITAKE TSUTOMU
IPC: B22D11/06
Filed: 1984-07-24
Abstract: PURPOSE:To provide a titled device which increases the effect of cooling quickly an ejected melt in quick cooling, by a roll, of a molten liquid by using a thin optional material having excellent adhesiveness and wettability to form the outside circumferential surface of a highly heat-conductive roll. CONSTITUTION:A stainless steel film having the good adhesiveness and wettability to the melt is formed to the outside circumferential surface of the water- cooled highly heat-conductive roll made of copper to <=1mum by a vapor deposition or thermal spraying method. Since the film is extremely thin, the quick cooling effect of the roll is not decreased; in addition, the heat conductivity of the melt is much improved by the adhesiveness and wettabiliy of the film. The effect of cooling quickly the ejected melt is thus additionally improved and the melt is satisfactorily made amorphous.

Title: Production of ultrahigh performance silicon steel, and its intermediate product, and ultrahigh performance silicon steel product
Inventor: HONMA HODAKA
IPC: H01F1/147
Filed: 1995-05-17
Abstract: PURPOSE: To easily and stably produce an ultrahigh silicon steel excellent in magnetic properties but difficult to manufacture. CONSTITUTION: A powder mixture is prepared by mixing powdery Fe and Si, containing inevitable impurities, in the proportion where the amount of Si becomes <=7% by weight. This powder mixture is filled into a vessel composed of easily cold-workable metallic material and having a thin layer, facilitating the separation of the powder from the vessel, on the internal surface, in the position between the powder and the vessel. Then, the powder is subjected, together with the vessel, to cold rolling, to cold forging, or to cold drawing. In this method, the draft of the powder layer is regulated to >=70% by reduction of area, and further, annealing is done in the course of or after cold rolling. By this procedure, the ultrahigh silicon steel excellent in soft-magnetic properties can be produced, and also the intermediate product before the annealing and the final product can be produced.  By this method, the ultrahigh performance silicon steel sheet having extremely high silicon content, without causing brittle crack, brittle fracture, etc., can be easily produced.

Title: Power supply circuit device
Inventor: OKIMURA KIMIHIKO
IPC: H02J1/00
Filed: 1992-06-15
Abstract: PURPOSE:To prevent the voltage converted through a step-down voltage converting circuit from lowering even when the load current drops below a rated range by feeding the output current from a step-up voltage converting circuit through a rectifying element to the step-down voltage converting circuit even when the load current exceeds the rated range. CONSTITUTION:Upon provision of an operational command to any one of drive motor, paper feed motor, or head section in a printer, a decision is made that the power supply voltage has dropped and a control circuit 16 operates a step-up switching regulator 11 to feed a step-down regulator 14 with an output voltage converted to 18V. The regulator 14 converts input voltage of 18V into 9V which is then fed to the step-down regulator 12. Consequently, even if a machine consuming high power operates to cause power supply voltage drop, a converted high voltage is fed from the regulator 11 to the regulator 12. At that time, counter flow to the power supply 20 is blocked by means of a diode 13.
